7 is a perspective 4view of a type slug provided with rule -engaging 'lugs formed by the use of matrices made in accordance with my inventiongfF ig. 48 .is` Va perspective view of a ruled type form illustrating the use of the rule engaginglugs; Fig. 9 is an enlarged v1e\v of a. portion of-a type slug illustrating a pair of rulev holding lugs before Abeing bent to' engage the rule; and-'F ig. l0 isa view similar toFig. 9 but illustrating the 'lugs as bent into engagement with .a triangular rule.

In said drawings- 10 represents a matrix of the usual lmotype form having recesses 11 of peculiar shape in one of its edges adapted to form or produce lugs 'of peculiar shape ,upon and rising from thel face of the type slug which is ca st in the linotype.v machine. V In Fig. 2 thematrix IOisSShQWIl-.ll position betweenvise jaws 1 2 and 13, the au 13 being provided' with a slot.4 14 inwhich the body of the slug isformed..- .'I`helface of the vis jaw-and the coacting face or edge ofv the matrix are coincident with the face ofthe slug formed by thecoperation ofthe 4 jaw and the matrix. The recesses 1 1@ are'indi cated as being in position directly in front of the mouth of the slot 14 whereby theplugs produced by the recesses tvill be formed upon -the face of the slug.' In casting-@the slug, the molten type metal is forced through the nozzle lfllling the slot 14 and .the recesses ll, in the usual manner. g l

As clearlyv illustrated in Fig. 5 which iS an enlarged horizontal section of the slug and matrix, the recesses l1 are V- shaped and' are formed to produce thin lugs 1.6.-u'ponfthe slug 1T. These lugs 16 have their; inner faces arranged parallel with each Otherand are formed with thin or knife .edges and being thin are adapted to be 'easilyformed,-

its length adapted to form these longitu-` '105 dinally arrangedlugs.

My-novel form of matrix is adapted toi be associated with a plurality fmatrices having recesses -or molds "ini-,their 'Ledges adapted to fornr figures or. 'other characters similar to F ig. 5 but showing a line ofrmatf upon thellslug; "In 6. I have i illus-1' matrices be ftrated acompos'ed line of'matrices and the slug which would bevformed thereby, in a linotype machine. Some- .of these'matrices are provided with the ,lug .forming recesses 11 and others with the figure or character forming're `ceses-18, the composed line' of ing adapted to form the face of va complete linotype slug 17 having the rule holding lugs-16 thereon. associated in proper relation to printingcharacters 19 formed in the characterrecesses 18. The rule hold- .ing .lugs .16 as cle rly indicated in Fig. 6

are formed of'less height than the characters 19, so that, the edges of the lugswill not form or prlnt'an impression upon the surface printed by 'the slug; consequently the rule forming recesses 11 are'of less depth 'thanthe character forming recesses 18.

,In Fig. 7 I have illustrated atypical linotype slugprovided with several pairs of .rule holding lugs 16 ,spaced apart thereon in proper relative position to the va rious printing characters formed thereon.4

'The lugs 16 on 'the'slug in Fig. 7 and also in Fig. 9.are 'shown intheir-cast or original condition, and inFig. 1 0 I have illustrated' appair of. the lugs as they appear when bent o r pressed down upon the inclined -side faces ofthe line. printing rule 20.`

- In Fig. 8 l have illustrated a type form as 'composed ot a plurality of linotype slugs 17 ,each ot which is prov-idedwitha numberof pairs of rule holding lugs 16 formed thereon in proper relative position, so that 4when the slugs areA assembled. in column, the

lugs' on adjacent slugs form Vsubstantially continuous rule receiving slots, Vthese slotsl being adapted to receive the rules 20 which rest upon the upper faces 21 of the slugs and are supported thereby. After the rules 20'have been' placed in the slots, the lugs 16 are formed or bent to engage the inclined side faces of the rules and5 retain them in position-upon the type form.

While I have illustrated my'invention as particularly' adapted to .the production of linotype slugs having rule holding lugs, it is readily seen that the lug forming' recesses may be 'used Ain connection with other than the" linotype machines without departing from the spirit of the invention;l I therefore do not limit my invention to a linotype matrix having these recesses, nor do I wish to be confined toa matrix for the production upon aslug of a pair of associated rule: holding lugs as it will be readily seen that alternate slugs maybe formed with asingle rule holding lug in suchrelation to single lugs upon vassociated slugs, that the lugs will coact to retain.a"rule upon the type form. r

Having thus fullydescribed my invention, I claim as new and desire to secure by Letters Patent:
